Windows 10: Laptop display goes off but computer still running

Hello

I hope somebody here can help me with my problem.
The display on my laptop sometimes disappears but the computer is still running. It only opens when I have been away and never when I'm actually using it. I can see that the computer is still on because the power lights are still on and the fan is still spinning. There are days that it doesn't happen and other days it can happen three or four times. I have to hold down the power button and restart which probably isn't good for my laptop.
My laptop is always plugged in and my power plan, shown in the image, is set to go off after 30 minutes.


I'm grateful for any advice.
Thanks.

:)

 

Laptop display question

Confusing statement! You want to change the display on your laptop that died?

Is that correct?

How do you know its the display that's bad?

Just google "how to change display on a acer 5745"

Should get you to step by step instructions. But first make sure its the display that's bad

Laptop display does not detect itself

Hi,

I only have 1 computer (the laptop) and 1 external monitor. The laptop cannot detect its own screen.

So when I follow your steps, this is what happens:

• Go to Settings. (Done)
• Click on System. (Done)
• Under System, choose Display. (Done)
• Under Multiple displays, click on Duplicate these displays and apply. (Done)
• But then I undock my laptop and redock. Re-login, etc.
• Only the external display turns on. The laptop does not turn on its own display. In order to get the laptop display to wake up, I need to follow steps 1-4 again. The settign "Duplicate these displays" does not seem to be retained.
